The invention discloses a kind of method of cotton brocade union iron rust etching, include the following steps: that pad → decatize etching → washing → dyeing → reduction cleaning → is rolled soft → with hydrogen peroxide dries setting → finished product to fabric preparation → pre-setting → with iron rust water printing →.Cotton etching in the present invention does not use the concentrated sulfuric acid, and uses iron rust, reduces cost, turns waste into wealth；Etching and one step of pre-treatment are completed, and process flow, energy conservation and environmental protection are shortened；There is pierced pattern at etching in two kinds of fiber interweavings, and three-dimensional sense is strong.Polyamide fibre is only contaminated in the present invention, has color at pierced pattern, and hollow part is not white, generates unique double-colored pattern effect. |
